It’s no exaggeration when we say that things are happening in a lightning-fast manner in tech space nowadays, especially in terms of IoT devices.
According to IoT Analytics, the number of connected IoT devices across the world could possibly reach a whopping 39 billion by 2030, which is an equally huge jump of 13.2% CAGR from 2025. So, imagine the sheer amount of pressure on enterprise networks if everything were to rely on cloud computing. That’s where Edge AI (artificial intelligence) comes in, deftly handling data processing directly on devices.
It essentially deploys AI models and algorithms directly onto local edge IoT devices, allowing real-time processing and analysis of data and information without having to constantly rely on cloud infrastructure.
Basically, every great innovation we see around us today, whether it’s smart home appliances, security cameras, wearable devices, or self-driving cars, they all employ edge AI capabilities to deliver real-time information to users. So, when it comes to brass tacks, edge AI is one of the biggest driving forces behind some of the greatest tech innovations. This article delves into the world of edge AI, and examines what makes edge AI so important and revolutionary today.
An Introduction To Edge AI
Edge AI, which basically is AI on the edge, is the process of deploying AI applications in devices across the physical world. It essentially blends the concepts of AI and edge computing to perform machine learning (ML) tasks on interconnected edge devices directly. Hence, the process allows storing data near the device, with AI-powered algorithms processing it at the network’s edge and not necessarily requiring an internet connection.
So, data processing is done in a matter of milliseconds. The reason it’s called “edge AI” is because the AI computation is done at the “edge” of the network, close to where the data is located and near the user, as opposed to being done centrally in a private data centre or cloud computing facility. And since the internet reaches practically everywhere in the world, the edge of the network could connote any location, whether it’s a hospital, a factory, a retail store, an office, or any of the devices all around us, like smartphones, autonomous machines, and even traffic lights.
Interestingly, the origin of edge AI dates back to the 1990s, when content delivery networks were created to serve video and web content from edge servers and deployed close to users.
How Is Edge AI Different From Cloud-Based AI
The main difference between Edge AI and traditional cloud-based AI is mainly how machine learning models are processed and deployed in both models. In a traditional AI setup, which relies heavily on cloud-based infrastructure, data is sent to remote servers that need powerful resources such as GPUs. Thus, this approach often sees issues such as constant internet dependence, security concerns, and latency.
On the other hand, Edge AI processes data locally on devices such as IoT sensors and smartphones, significantly reducing latency and providing much faster real-time responses. Since it keeps information on the device, not only does it improve data privacy, but it also minimises bandwidth usage, making it ideal for cases where internet access is unreliable or limited.
Edge AI: The Relevance And Use Cases
Organisations from practically every sphere of the industry are looking to increase automation to improve safety, efficiency, and processes. In order for that to happen, patterns need to be recognised to execute tasks safely and repeatedly, but the unstructured world and a wide range of human-performed tasks make it challenging. This is where Edge AI steps in, learning to perform similar tasks under different circumstances efficiently.
Take virtual assistants and smart speakers, for instance. Edge AI is intrinsic to the working of the always-listening features in devices such as Google Home and Amazon Alexa. The local processing provides prompt real-time responses, which is critical for these functionalities to work successfully. Then there’s wearable devices such as fitness trackers and smartwatches for fitness and health tracking that employ Edge AI to monitor physical activities and sleep patterns. In fact, many of these devices run simple models right on the device. For instance, Edge AI can track sleep and count steps locally and even offer the user efficient and fast feedback.
That’s not all; even the manufacturing industry employs Edge AI, especially for supporting defect detection such as misaligned pallets and packaging errors using smart cameras. Then there’s predictive maintenance for machinery by analysing sensor data such as sound, vibrations, and electrical current to monitor machinery for potential issues. And, of course, who can forget the ever-in-vogue robotics and autonomous vehicles? They rely heavily on Edge AI for decision-making in fast-paced environments where stable internet connections aren’t a guarantee.
In fact, most of the processing such as object recognition, obstacle detection, and navigation takes place directly on the robot or the vehicle.
We’re just in the early innings of Edge AI, and the possibilities for its applications are seemingly endless. According to Gartner data, merely 10% of data was processed on the edge in 2021, a number that jumped to a whopping 75% by 2025. As neural networks mature commercially, advances take place in 5G and parallel computation, and the proliferation of IoT devices explodes, there’s now robust infrastructure for generalised machine learning.
It’s what’s allowing enterprises to capitalise on the colossal opportunity to bring AI to the edge, right next to their place of business where it can make decisions based on real-time insights, all while increasing privacy and reducing costs.
